This study analyzed the relative operational efficiency and impact factors of regional public hospitals to present benchmarking points for enhancing the efficiency of inefficient regional public hospitals. The survey targets collected and utilized the internal resources and management performance data from 34 regional public hospitals in Korea over the past five years, from 2014 to 2018. The final 33 regional public hospitals were surveyed, excluding Jinan Regional Public Hospital, which opened in 2015, the middle of the survey period. The general characteristics and input/output variables were analyzed by frequency analysis and technical statistics analysis, and Data Envelopment Analysis was performed to measure the operational efficiency index and relative comparison. According to the study, there were 11 efficient hospitals (33.3%) and 22 inefficient hospitals (66.7%). Of the 22 inefficient hospitals, 13 (IRS: Increasing Returns to Scale) required scale expansion, and nine (DRS: Decreasing Returns to Scale) required scale reduction or rebalancing. The significance of this study was that an analysis of the relative efficiency and influencing factors presented specific alternatives or directions that could help enhance the efficiency of the growth of regional public hospitals, sustainable management, and expansion of publicness.

Currently, there are many simple searches for local culture and tourism, but systematic information retrieval using ontology technology is weak. The keyword-based search, which is an existing search method, derives a search result that is different from a user's wanted intention. On the other hand, semantic search using ontology constructs shows the information related to the search term by creating a relation between words and words. Therefore, when tourists search for cultural and tourist attractions in the area, they provide information that includes meaning relevance in the search results. If the ontology provides information on the culture, sightseeing area, transportation, Can be more easily grasped. In this paper, we propose an ontology-based retrieval system based on culture and tourist sites utilizing public institutions database by using mobile application by extending search system which relied only on existing internal database to provide accurate and reliable information to users. This efficient structure of the ontology makes it possible to provide information suitable for the user quickly and accurately.

Assemblypersons' activities have organizational and individual nature. The activities of assemblypersons and their assistant staffs become a motive for major work performance of Korean legislature, and are also critical public services affecting contemporary political history, history of political parties and history of assemblyperson's hometown. Moreover, their activities are also characterized by work performance in favor of assemblyperson's personal interests to effectively communicate his or her achievements during term of office to electors with a view to winning reelection after the end of 4-year term of office. Assemblyperson's organization produces various types of record in the performance of these works. From the viewpoint of public archive as a product of assemblypersons' public service performance and from their own personal viewpoints, they can create their own identity by arranging their personal records that can demonstrate their own political philosophy, policy orientation, achievements during term of office, and personal features. In addition, their personal records can have much more values and significance in the sense that those records are available to electors to make it possible to highlight their own images in objective and reliable manner. Conclusively, this study underlined that the efforts for assemblypersons and their assistant staffs to keep their records well could be helpful to streamline their internal works and be also helpful for personal interests of assemblypersons. And this study proposed procedures and methods for deducing and screening a list of production archives to meet a viewpoint of streamlined internal works and needs for keeping personal records, ultimately with a view to giving practical helps for these works.

This study surveyed and compared the temperature distribution in domestic refrigerators and freezers used in Korea to determine whether temperature varied according to the location of food storage. We selected 50 people to collect temperature data; among them, 25 measured the temperature of refrigerators, while the remaining measured the temperature of freezers. Consequently, the lowest and highest temperatures measured in domestic refrigerators were found to be -8.2℃ and 15.8℃, respectively, with an average temperature of 3.73℃. The temperature distribution based on internal location was: 5.06±1.69℃ for the door storage compartment, 4.18±1.19℃ for the inside wall surface, and 3.41±1.36℃ for the inner storage box. Significant temperature differences between the top and bottom were only identified at the door storage compartment (P<0.01). Further, the minimum and maximum temperatures measured in the freezer was -30.3℃ and 0.7℃, respectively, with an average temperature of -17.95℃. The temperature distribution based on location was: -17.19±1.68℃ for the door storage compartment, -17.81±1.07℃ for the inside wall surface, and -18.78±1.72℃ for the inside storage box. The results were similar to that of the refrigerator, with the lowest temperature in the inside storage box, and a significant temperature difference between the top and bottom noted only at the door (P<0.01). The maximum temperature difference (between locations) within the refrigerator and freezer was found to be 2.18 and 2.02℃, respectively. In conclusion, the temperature in the entire space was not constant; there were significant deviations at different storage locations. Therefore, public authorities should actively advise customers on the recommended storage locations for each food type. People will benefit from awareness about storage management, including avoiding storage of temperature-sensitive foods in door compartment.

The positive changes in urban space and urban activities resulting from the urban services provided by Smart City is not accomplished by simply creating the physical environment built on ICT but through the cooperation and participation of citizens and private sector, which is in fact key to success. In this study, this research analyzed the role and structure of smart governance, which is a system of horizontal cooperation between public and private sector, and analyze its role in developing Smart City. The study also proposes various ways to facilitate such development in each of critical categories. For this purpose, this research studied 228 smart services across 11 categories registered in the Ministry of Land and Transport in Korea to analyze the spatial distribution of smart services by spatial hierarchy and their characteristics Also, the research conducted a case study of MetroGIS, which is an information collaboration governance system for the greater area of Minneapolis and St. Paul in the state of Minnesota, United States, to explore how governance is formed; its organizational structure; the role of sub-level organization hierarchy and their interrelationship. The results of the analysis suggest that the following conditions are required to create a smart city: first, public sector resource assistance for building community; second, enhanced communication system within the community and with outside the community; securing financial stability and establishing a model of sustainable development to induce the community to evolve into a governance form.

Wireless networks make the users' work more convenient and efficient, but such networks can impair the availability of network resources and can cause leakage of important corporate information when there are security threats. In particular, damage has increased because of security attacks that take advantage of the vulnerabilities created by a wireless AP (Access Point). Public organizations and companies have gradually selected the WIPS (Wireless Intrusion Prevention System) to block wireless security threats and protect the internal network. However, it is very costly for other organizations and companies to introduce the WIPS solution. This paper proposes implementing a WIPS Sensor by using Raspberry Pi to reduce these costs and to block the various wireless LAN security threats. This implementation would protect corporate information and provide consistent services at a relatively reasonable price.

The right to know is not satisfied merely by making or improving laws or systems. The right to know is a matter of culture rather than system. Nevertheless, consistent system improvement measures are required. There are many laws relating to the right to know. In particular, at the core are the Official Information Disclosure Act, the Record and Archives Management Act, and the Presidential Record Management Act. The fact that systems relating to official record management and presidential record management are related to the right to know is understood by the promotion of records and archives management reform after the year 2004, as a result of which the national archives management innovation road map was established. Reflecting the many opinions of the "Information Disclosure System Improvement Task Force" composed with participation of the government and the press after the participatory government's announcement of "Measures to Advance the Support System for News Coverage," amendments to the Information Disclosure Act have come forward with system improvement measures in connection with issues that had arisen until then. Such improvement measures have not resulted in actual improvements. This thesis proposes several system improvement measures, focusing on those that have arisen until now but have not been reflected in discussion, such as converting the concept of information non-disclosure into disclosure postponement, preparing and disclosing particular information disclosure standards, specifying personal information for non-disclosure, specifying and strictly applying any information that has not been disclosed for purposes of internal review, deleting non-disclosure items in stenographic records that do not have a reason to exist, and establishing limits and terms of non-disclosure. Of the most remarkable system improvement measures that have been made until now is our recognition that the right to know is not limited to the information disclosure system but that the "cause" of archive management should be systematic and scientific. In other words, the right to know is understood to establish not just accidential factors, such as with a whistle-blower, but the inevitable factors of systemization of production, distribution, preservation, and use of archives. Much more study should be pursued regarding disclosure of archives information. In particular, difficult issues to be resolved regarding reading records at permanent archives management institutions, such as the National Archives of Korea, or copyrights that arise in the process, require constant study from academia and relevant institutions.

The archives preservation chamber is an equipment that is able to store important archives with air-cleaning and isothermal-isohumidity control functions to permanently store archives in a highly safe environment. The chamber can only store small amounts of archives but it is crucial for organizations preserving archives to economically store a variety of archives, be it a medium or a small amount of documents. An arm of this study researches the current preservation status of the local record center to determine the need for such a chamber. In addition, in order to improve the air-cleaning and isothermal-isohumidity functions, the researchers of this study have conducted analyses to design the core parts. The preservation chamber that had been designed includes an archives preservation area, air-cleaning equipment, and environment measurement equipment. A preservation chamber is used to preserve small amounts of important archives safely. Thus, when a local record center is preserving various types of archives in small or medium quantities in a stack room, the preservation chamber can be used to aid their long-term preservation.

Recently large amounts of customer information has leaked ranging from public institutions to the large-scale of portals, and similar information leakage incidents owing to the absence of personal information management have subsequently occurred. Therefore, the security infrastructure in which leakage of internal data can be blocked fundamentally is emerging as a key issue. An integrated identity and access management architecture which performs user access and its rights management, authentication and audit of the business systems is more important to improve the efficiency of business. In addition, this approach is emerging as a safe and effective ways for identity and access rights management. In this paper, we analyze how an integrated approach for identity and access management to improve the efficiency of the computational work and to strengthen the security in local government administration should be constructed, and proposed the preferred solution.
